CVE-2026-75846: Missing Authorization in ArcadeData arcadedb
ArcadeDB versions up to 26.7.3 have a missing authorization vulnerability in the DELETE FUNCTION SQL statement. This flaw allows any user with database access to delete server-side functions without proper permission checks, potentially impacting the database's integrity and availability.
AI Analysis
Technical Summary
CVE-2026-75846 describes a missing authorization vulnerability in ArcadeDB before version 26.8.1 (affected versions up to 26.7.3). The DELETE FUNCTION SQL statement's execution path (DeleteFunctionStatement.executeSimple) unregisters and persists the deletion of server-side functions without performing a checkPermissionsOnDatabase (UPDATE_SCHEMA) authorization check. Consequently, any user with access to the database can invoke DELETE FUNCTION via the command API (POST /api/v1/command/{db}) to remove registered server-side functions, including those critical to security logic, thereby compromising the integrity and availability of the database.
Potential Impact
An attacker with database access can delete any server-side function without authorization, including security-relevant functions. This can lead to loss of critical logic, undermining database integrity and availability. The vulnerability does not require user interaction or elevated privileges beyond database access.
Mitigation Recommendations
A fix is available in ArcadeDB version 26.8.1. Users should upgrade to version 26.8.1 or later to remediate this vulnerability. No other mitigation guidance is provided; patching is the recommended action.
